However, their widespread usage emphasizes the critical need to enhance their security posture to ensure the integrity and reliability of their outputs and minimize harmful effects. Prompt injections and training data poisoning attacks are two of the most prominent vulnerabilities in LLMs, which could potentially lead to unpredictable and undesirable behaviors, such as biased outputs, misinformation propagation, and even malicious content generation. The Common Vulnerability Scoring System (CVSS) framework provides a standardized approach to capturing the principal characteristics of vulnerabilities, facilitating a deeper understanding of their severity within the security and AI communities. By extending the current CVSS framework, we generate scores for these vulnerabilities such that organizations can prioritize mitigation efforts, allocate resources effectively, and implement targeted security measures to defend against potential risks.展开更多

We also construct a convergent sequence { Xn } n c∈Nby the quasi-contractive conditions of { Tn } n ∈N and the boundary condition of a given complete and closed subset of a cone metric space X with convex structure, and then prove that the unique limit x" of {xn}n∈N is the unique common fixed point of {Tn}n∈N. Finally, we will give more generalized common fixed point theorem for mappings {Ti,j}i,j∈N. The main theorems in this paper generalize and improve many known common fixed point theorems for a finite or countable family of mappings with quasi-contractive conditions.展开更多

It specifically looks at the process and factors that characterize the dynamics of the above interactions, with particular reference to the changing status and governance of CPRs at community levels. The paper puts together the synthesis of observations and inferences of different studies by ICIMOD and others in mountain regions, particularly in different parts of Nepal, India, Bhutan, Bangladesh, China and Pakistan. Rural CPRs (providing sustenance supplies and services) as an important component of a community’s natural resource base, manifest the institutional arrangements evolved by the communities to facilitate their adaptations to nature. The above process can be more clearly illustrated with reference to specific characteristics of mountain areas, called mountain specificities. However, over time, the situation of CPRs in terms of their extent and status, governance and management as well as contributions to community sustenance, has changed. The paper attempts toindicate potential lead lines for searching options for rehabilitation of CPRs, based on a closer under- standing of the factors contributing to their decline.展开更多

The first condition is primary, and is the motivation for classification and the evidence of a genetic relationship. The second condition is secondary and supportive, and is the feature,approach and sign of a language group. This article focuses on common innovations in the Sino-Tibetan language family. Tone, voiceless aspirated stops, affricates, classifiers, noun prefixes for kinship and overlap are six common innovations that are proposed for defining the Sino-Tibetan language family.展开更多

Linguists have carried out many theoretical and empirical studies with a sharp purpose to promote Second Language Acquisition. Krashen's Input Hypothesis and Long's Interaction Hypothesis are most influential ones among the studies. They both play important roles in language teaching and learning. The paper will present an account of the two great theories, including the main claims, theoretical foundations as well as some related empirical works and try to investigate commons and differences between them, based on literature and empirical studies. The purpose of writing this paper is to provide a clear outline of the two theories and point out how they are interrelated yet separate predictions about how second language are learned. It is meaningful because the results can be valuable guidance and highlights for language teachers and learners to teach or acquire a language better.展开更多

The 1RS chromosome from the German cultivated rye variety Petkus is critical in wheat breeding. However, its weakened disease resistance highlights the need to identify new resources. In the present study, a novel derived line called D27 was developed from common wheat and Mexico Rye.Cytological observations characterized the karyotype of D27 as 2n=42=21 Ⅱ. Genomic in situ hybridization indicated that a pair of whole-arm translocated Mexico Rye chromosomes were inherited typically in the mitotic and meiosis stages of D27. Experiments using fluorescence in situ hybridization(FISH) and gliadin electrophoresis showed that D27 lacked wheat 1DS chromosomes. They were replaced by 1RS chromosomes of Mexico Rye, supported by wheat simple-sequence repeat markers, rye sequence characterized amplified region markers, and wheat 40K SNP array analysis.The wheat 1DS chromosomes could not be detected by molecular markers and wheat SNP array, but the presence of rye 1RS chromosomes was confirmed. Agronomic trait assessments indicated that D27 had a higher tiller number and enhanced stripe rust and powdery mildew resistance. In addition, dough properties analysis showed that replacing 1DS led to higher viscosity and lower dough elasticity in D27, which was beneficial for cake making. In conclusion, the novel cytogenetically stable common wheat–Mexico Rye T1DL·1RS translocation line D27 offers excellent potential as outstanding germplasm in wheat breeding programs focusing on disease resistance and yield improvement. Additionally,it can be valuable for researching the rye 1RS chromosome’s genetic diversity.展开更多

The paper therefore analyses the CBNRM framework as a strategy for implementing sustainable tourism and poverty alleviation initiatives in Botswana, Namibia, and Zambia. The article specifically underscores the importance of local-level participatory management and utilisation of natural resources in the region. Paying special attention to the previous researches that have been conducted in Botswana, Namibia, and Zambia, the methodological approach employed in the paper centres on critical discourse analysis and review of literatures to highlight the interface existing between CBNRM and rural (tourism) development. The analytical framework of the paper is thus rooted in the Common Property Resource (CPR) theory Overall, the authors argue that tourism, poverty alleviation, rural development, and sustainable natural resource use are linked and interrelated in the process of enhancing community well-being. Findings indicate that CBNRM initiatives have had a significant and positive impact in achieving sustainable tourism, rural development, poverty alleviation, and natural resource management. Specifically, findings show that the CBNRM has contributed to the reduction in wildlife poaching. While other pertinent issues remain, national governments in the three southern African economies need to fully appropriate the benefits that CBNRM offers and improve on them for better implementation of developmental programs.展开更多

Especially where biodiversity loss appears and ecosystem services (ESS) decline, the lack of public management might be related to inappropriate institutional setups. Two distinct directions of thought prevail on the subject. On one hand, proponents of property rights and minimal state intervention eagerly analyse the feat of modern institutions and view private property and payments for ecosystem services (PES) as solution. On the other hand, common pool resource management (CPM) has regained interest because nature is not a straight commodity and cooperation in ESS provision is needed (partly also to facilitate PES). In this paper, the two aspects are combined in a hybrid institution. We suggest a new way of approaching institutional questions in ESS provision as synthesis of private and publically controlled ESS provision. It is contemplated as ESS governance of local eco-nets given the potential for inclusion of public management. In principle, the result is a controlled framework of land sharing between farm land (private ownership) and communally managed?land (public ownership). Some land is devoted to hedges, wetlands, etc. Land is an immobile resource and can be used for EESs based on planned species prevalence, whereas communities compete also for labour which can move (or not). Governance is acting in competing constituencies and is a mean to control the regulating entities (public ESS management). At a meta-level we combine the need for public management with advantages of a competitive neo-classical framework. This contribution to CPM investigates a model of a group whose well-being is based on ESS provision in a cultural landscape. By statutory regulations, land (field margins), is ex-tracted from farms for ESS;in particular a leader (called reeve) guides farmers. Two institutions are compared: (1) labour in public land for ESS based farming (i.e.?it is controlled by public authority), or (2) it can migrate seeking higher rents in neighbouring communities.展开更多

New properties of the genetic code are presented and its most important integral characteristics are established. Two groups of such characteristics were distinguished. The first group refers to the integral characteristics for the areas of DNA, where genes are broken down in pairs and all 5 cases of overlap, allowed by the structure of DNA, were investigated. The second group of characteristics refers to the most extended areas of DNA in which there is no genetic overlap. The interrelation of the established integral characteristics in these groups is shown. As a result, a number of previously unknown effects were discovered. It was possible to establish two functions in which all the over-understood codons in mitochondrial genetic codes (human and other organizations) participate, as well as a significant difference in the integral characteristics of such codes compared to the standard code. Other properties of the structure of the genetic code following from the obtained results are also established. The obtained results allowed us to set and solve one of the new breakthrough problems—the calculation of the genetic code. The full version of the solution to this problem was published in this journal in August 2017.展开更多

It had a higher nutritional value (higher fibre content and protein retention] (p 〈 0.05) and better cooking characteristics (higher cooking yield and moisture retention) (p 〈 0.05) than the control. The colour (a*, b*) increased; lightness and whiteness index decrease (p 〈 0.05). Hardness increase (p 〈 0.05) occurred because of CSF addition. Differential scanning calorimetry showed that fibre fortification did not interfere with the thermal transitions of the restructured meat. No significant differences were detected with the preference test scores of 4% or 8% CSF compared with the control. Restructured (4%-8% CSF) had a higher content of fibre and fat, which could be linoleic and linolenic acid, and an increase in the content of protein compared with those of commercial products, among had 1.62 and 2.25 mg AGE/g. Therefore, the restructured properties of common carp were governed by CSF addition.展开更多
